[Buildroot] [PATCH 29/29 v2] package/fx2lafw: new package

[Yann E. MORIN]

fx2lafw (FX2 logic analyser firmware) is a set of firmware files for
FX2- or FX2L-based logic analysers. It is developped by the Sigrok
project.

The latest release, 0.1.7, is more than 5 years old now, and no longer
builds with recent sdcc versions (starting with 4.2.3). The git tree has
fixes for those build failures. Rather than backport the 4 commits of
interest, just use the git tree directly: it contains another unrelated
fix, a few documentation changes, and two new firmwares. Also, given the
git tree has not been touched since early 2024, and given the frequency
of releases before that, don't wait to get those two new firmwares.

fx2lafw bundles fx2lib. Usually, we'd avoid using a bundled version, but
in this case, it is an old version, and anyway fx2lafw can't use a
pre-installed version. The probability that another package would use
fx2lib is extra slim as well; if we eventually get one, the chances it
also bundles its own copy are also relatively high. And finally, fx2lib
runs on a separate microcontroller, not on the target's main CPU, so it
can't be shared to any "real target" package. There is no reason to
expand the efforts to unbundle it.

sigrok.org's IPv6 is unresponsive, and as it is the first one tried when
connecting, this causes a huge delay when fetching; indeed, our git
backend does at least three git-fetch, each timing out after ~135s, for
a total of ~400s, plus the time of download (which is fortunately rather
small for this package). So, force use of IPv4.
